@jimunderscorep I tried the command and it says: snap "opera-stable" is not installed. That is funny, I have it installed so I wonder why it says it isn't there. Is there some association I need to do in order for it to recognize the program?

@jimunderscorep Will do. Thank you very much for the help. I didn't remember how it got there...so thought it came with it. Ubuntu frustrated me at first...so that may be where the confusion muddled my memory. Thanks again.

@ctrlaltdel Thanks for responding. I have downloaded this program in both Windows 10 and Linux. The Windows version works as you describe, but the Linux version does not. I am not given a choice for the program in Linux when I try to use a magnet to download. I must be missing some step to connect qBittorrent with torrent downloading in Linux when a magnet is clicked. I am still looking everywhere for a solution.

Have latest Opera browser and Ubuntu 18.04 and want to use qBittorrent or even Deluge to get torrents via magnet links...how do I set up? I try and get a box that pops up: xdg-open with 2 boxes for choices. Neither are very helpful. Any clues? Treat this as a request from a newbie to Linux. Thanks.
